nRF2460 TDD Signal?

[diode]

Is there a signal provided by the nRF2460 that indicates TX/RX state of transceiver suitable for controlling direction of an FEM? Does VCC_PA turn on and off during duplex operation? Might the SYNC signal used for receiver sync be helpful?

Hi

As I mentioned in the other case you can use the VDD_PA pin to control an external PA.

There is no similar signal for the RX unfortunately, but the naive approach would be to simply invert the VDD_PA pin and use that to control the LNA.
